So I left the house to go to the dentist this morning. On my way at a red light, it died on me. I just filled up yesterday, and has been running like a champ for me for the three months I’ve been driving it since my dad died, so I was thinking maybe it was a batch of bad gas. When I left the dentist I start it, it would die, start it, died. No codes, no lights, nothing. If I could keep it running if I gave it some gas, so being a few miles from home, that’s what I did. On my way home, that’s when lights on the dash started popping up like “Service Parking Brake” and “Service ESC” and “Steering Assist is Reduced, Drive with Care.” Both the “traction control off” light and the parking brake with a key underneath it light was on, and the CEL was flashing. I pulled the codes when I got home and had codes P0152 (O2 sensor bank 2, sensor 1), P0157 (O2 sensor bank 2 sensor 2), and P0300 (random misfire).
Now I know everyone’s response is going to be “It’s a 2020 with 10k miles, it’s under warranty, take it to the dealer.” and that’s what I will be doing as soon as I can. My question is, has anyone had this happen to them before or seen this before in their AT4? I’ve had this exact thing happen to me before, but it was in my 2004 GTO after I put the headers on it, and I blew out two of the O2 sensors because I didn’t seal the wires properly (you have to extend the O2 sensor wires whenever you put headers on the newer GTOs, and I didn’t buy wire extenders, so I did it the old fashion way with bulk wire, butt connectors, and tape). But aside from adding a drop in K&N air filter, my AT4 is completely stock and unmolested. Hell, it’s only had the oil changed once. It was at the dealer for a couple months shortly after my dad bought it, something was bad in the transmission, and it took that long to get the part, but other than that, there’s been no problems with it.
